Iraq’s Prime Minister was staring into the abyss today after his operation to crush militia strongholds in Basra stalled, members of his own security forces defected and district after district of his own capital fell to Shia militia gunmen.

With the threat of a civil war looming in the south, Nouri al-Maliki’s police chief in Basra narrowly escaped assassination in the crucial port city, while in Baghdad, the spokesman for the Iraqi side of the US military surge was kidnapped by gunmen and his house burnt to the ground.

Saboteurs also blew up one of Iraq's two main oil pipelines from Basra, cutting at least a third of the exports from the city which provides 80 per cent of government revenue, a clear sign that the militias — who siphon significant sums off the oil smuggling trade — would not stop at mere insurrection.
